Burson Fouch: I remember in one flower shop there was a whole wall covered with poison ivy and people came from miles around to look at that wall and they stayed to buy. Gravis Mushnik: And the owner got rich? Burson Fouch: No, he scratched himself to death in an insane asylum.

Wilbur Force: No novocaine. It dulls the senses.

Seymour Krelboin: I'm getting pretty tired of you. Audrey Jr.: I need food. Seymour Krelboin: I don't care what you need. Look what you've done, you not only made a butcher out of me but you drove my girl away. Audrey Jr.: Shut up and bring on the food.

Although the film is legendary for having been shot in only two days, Jonathan Haze recalled in "The Little Shop of Horrors Book" that he was called back several weeks later for re-shoots.

Was remade as a successful stage musical that was later adapted into a film (Little Shop of Horrors (1986)).

Because of the lack of character names in the credited cast list, discussion has arisen about what's the spelling of Seymour's last name, with some variants being "Krelboyne", "Krelboined" (Mushnik's comical pronunciation) and "Krelborn" (the character's last name in the musical remake Little Shop of Horrors (1986)). Roger Corman, in his book "How I Made a Hundred Movies in Hollywood and Never Lost a Dime", confirms that the spelling is "Krelboin".

The manager of Producer's Studio informed Roger Corman that a large office set had been constructed for a production that was about to wrap. Corman arranged to use the standing set, redressed, as the main set of this film.
